在玻璃工业中,玻璃中的亚铁及总铁含量是一个重要的参数,其中铁(Ⅱ)能够强烈地吸收长波辐射,这对熔制过程的热传递以及最终产品的红外吸收性能具有明显的作用。高价铁使玻璃着成黄色或黄棕色,低价铁则使玻璃产生蓝绿色,玻璃的最终色调则取决于二者之间的比例以及总铁含量的多少。由于实际上玻璃中铁(Ⅱ)和铁(Ⅲ)总是同时存在的,铁(Ⅱ)一铁(Ⅲ)的平衡反映了玻璃的氧化状态。因此,知道铁的呈现形式对于控制玻璃的最终性质、研究玻璃的结构以及指导生产实践都具有重要意义。目前,对玻璃中铁的存在形式及比例的确定多采用两种独立的方法来完成:其一是按照美国材料试验标准(ASTM)所规定
In the glass industry, ferrous iron and total iron content in glass are an important parameter. Among them, iron (II) strongly absorbs long-wave radiation, which has obvious effects on the heat transfer in the melting process and the infrared absorption of the final product effect. High-priced iron makes the glass yellow or yellow-brown, low-cost iron makes the glass produce blue-green, the final color of the glass depends on the ratio between the two and the total amount of iron. The fact that the iron (II) and iron (III) are always present simultaneously in the glass, the iron (II) -iron (III) balance reflects the oxidation state of the glass. Therefore, knowing the form of iron is of great importance for controlling the final properties of the glass, studying the structure of the glass and guiding the production practice. At present, the existence of iron in the glass form and the proportion of more use of two independent methods to complete: one is in accordance with the American Society for Testing and Materials (ASTM)
